An Najah National University Building Engineering Department Potential Energy glazing Technologies For Highly Glazed

1. An Najah National University Building Engineering Department Potential Energy glazing Technologies For Highly Glazed Buildings in Palestine Prepared by : Fuad Mutasim Baba Murad Ribhi Bsharat Wala' Hasan Omar Supervised by: Dr. Sameh Monna

2. Project ContentWhy did we choose this project ?What are the types of facade used?What are the strategies for improving indoor environment in such buildings ?What are the effects of each type of facade on Indoor Environment?What are the Glass facade Construction and other elements?What are the effects of each type of facade on the cost?What is our Future work?

3. Why did we choose this project ? Architects, designers, owner, and consultant tend to use large glazing area today more than ever before by using Single skin façade. Without consider the impact of this type of facade on:

18. Environmental Analysis

19. Environmental Analysis • Heating and cooling loads • Natural Ventilation • Daylight • Acoustics

20. Heating and cooling loads We used Design builder which is a simulation software for thermal analysis which is based on Energy Plus software.

21. Heating and cooling loadsTraditional façade There are two condition in this case * Un-insulated Building with double clear glass. *Insulated building with Low emissive glass.

22. Thermal properties for Un- insulated building The Heat transfer coefficient U for wall=1.5 W/m2.K The layer of wall in Un-insulated building by Design builder Software
